What does the solar term in Grain Rain mean?

Every year from April 19 to April 2 1 day, when the sun reaches 30 degrees of the Yellow Meridian, it is a Grain Rain with 24 solar terms, which comes from the old saying "Rain gives birth to hundreds of valleys". Grain Rain is also the best time to plant seedlings, grow melons and order beans. "Qingming Snow Rest, Grain Rain Frost Rest". Grain Rain is the last solar term in spring, and the arrival of Grain Rain solar term means that the cold wave weather is basically over, and the temperature rises rapidly, which is very beneficial to the growth of cereal crops.

In ancient China, Grain Rain was divided into three stages: "The first stage was when Ping was born, the second stage was when pigeons flapped their wings, and the third stage was when Dai Sheng came down to mulberry." After Grain Rain, rainfall increased, duckweed began to grow, then cuckoo began to remind people to sow, and then Dai Sheng birds began to be seen on mulberry trees. "Tongwei Filial Piety Helps the Gods": "In the fifteenth day after the Qingming Festival, the bucket refers to Chen and is Grain Rain. In mid-March, it is said that the rain gives birth to hundreds of valleys, which are clean and bright. " "Qunfangpu" said: "Grain Rain, the valley is born with the rain." "Twenty-four solar terms" records: "In mid-March, after the rain, the ground paste pulsates, and now it rains its valley in water. Rain is silent, just like the rain in my field. At this time, cover the valley and sow, from top to bottom. " At this time, the weather is mild and the rainfall increases obviously, which has a great relationship with the growth and development of cereal crops. Appropriate rainfall is beneficial to rejuvenation and jointing of overwintering crops and sowing and emergence of spring crops. In ancient times, the so-called "rain gives birth to hundreds of valleys" embodies the significance of modern agricultural climate of "Grain Rain". However, too much rain or severe drought will often cause harm and affect the later yield. Grain Rain is in the middle and lower reaches of the Yellow River, which not only points out its agricultural significance, but also shows that "spring rain is as expensive as oil".

Grain Rain, as its name implies, is the valley that sowed Grain Rain. In other words, this is the best time for sowing, transplanting and ordering beans. Because the rainy season in Grain Rain will increase, which is very beneficial to the growth of cereal crops. Around Grain Rain, it is the best time for sowing, transplanting and ordering beans. As for what Grain Rain means, the ancients once said, "Rain gives birth to hundreds of valleys". According to meteorologists, Grain Rain is the last solar term in spring, and the arrival of Grain Rain solar term means that the cold wave weather basically ends, the temperature starts to rise, and the rainfall increases. During this period, rainfall plays an important role in the growth and development of cereal crops. Overwintering crops need rain to turn green and jointing, and spring-sown crops also need rain to sow and emerge, which is of great benefit to the growth of cereal crops, so it is called "Grain Rain".

What does the long summer solar term mean?

Long summer is a festival that reflects seasonal changes. Standing is the beginning, summer is the season. According to the traditional understanding, this is the beginning of that summer. Usually on May 5th or 6th of the Gregorian calendar.

On the day of the long summer, the sun moved to 45 degrees of the yellow meridian. At noon, the sun shadow was measured with standard meters, with a length of four inches, three feet and six minutes, which is equivalent to today's 1. 108 meters. Bucket handle, watching the Big Dipper at night, points to the third place, that is, the southeast direction. This stage is usually in April of the lunar calendar, also called Mitsuki, early summer, Huaixia and Xia Meng.

According to the standard of climatology, when the average temperature reaches 22℃ in five days, summer begins. In the middle and lower reaches of the Yellow River, the waiting temperature in the long summer season is close to the climatological standard, which is the origin of the twenty-four solar terms. From this point of view, it is practical to regard the Long Summer Festival as long summer in the 24 solar terms.

Long summer is divided into three stages. "At first, crickets sang." Cricket No.1, also called toad, is a kind of frog. At this time, frogs began to sing in the fields and ponds for food. "Wait for the earthworm to come out", because the underground temperature continues to rise, the earthworm climbs from the underground to the ground to breathe fresh air. "Third-class king melon", also known as sweet potato, has begun to grow and mature. Qing Qianlong's "Xinzheng County Records" contains: "April melons are picked and sold, and they are said to be fresh when given to each other." From these three descriptions, we can see the summer scenery.

Frogs generally live in places with water, especially near rice fields and ponds. Frogs can not only eat small creatures in the water, but also enjoy the cool under the straw. They can also look up and devour insects flying in the fields. When they are full, frogs will play drums and sing along with insects and birds in the trees. Earthworms crawl around the wetlands in the fields from time to time, and the wild king melons grow up and mature in the weeds, so they can be picked and eaten. If spring is a healthy season, then summer is a long season. Animals and plants on the earth have entered a period of vigorous growth. The temperature has risen sharply all over the country, and the rainfall has also increased significantly. The early rice in the south has tillered, and the rape has seeded and is about to mature. Winter wheat in the northern region is also flowering and filling. Spring-sown crops such as soybeans, corn, sorghum, millet and cotton have emerged one after another. Crops grow vigorously, and field management is increasingly busy. "Three dynasties are long and summer is everywhere". At this time, weeding can not only loosen the soil to prevent water evaporation, but also weed the fields. Therefore, there is an agricultural proverb "Don't hoe for one day, don't hoe for three days".
